Specify type of memory for storage of programmable coefficients for serial FIR filters


'Registers' (default)

Store programmable coefficients in a register file.


Store programmable coefficients in dual-port RAM.


Usage Notes

This property applies only to FIR filters that have one of the following serial architectures:

  • Fully serial

  • Partly serial

  • Cascade serial

When you use this property, be sure to set CoefficientSource to 'ProcessorInterface'. The coder ignores CoefficientMemory unless it is generating an interface for programmable coefficients.
